In the previous article, we talked about GDP as a measure for economic health. Unemployment is another way of doing it.

Unemployment Rate

Unemployment rate is not the percent of unemployed people in the United States. It’s the percent of unemployed people in the labor force.

Labor Force

The labor force is composed of everyone with jobs and everyone who is looking for a job. That is to say, the labor force is composed of all willing workers. Right now, the labor force of the United states is approximately 160 million. The rest are retired, kids, or just not looking for jobs for some other reason (e.g. illness).

What Causes Unemployment?

When real GDP grows slower than the labor force, the unemployment rate increases.

Damage of Unemployment

When unemployment is higher than the natural rate (around 4%), this means the economy isn’t producing at its potential. This means the production possibility frontier goes in.
